Development

Write modern, high-performance C# code using records, pattern matching, value objects, async/await, Span<T>/Memory<T>, and best-practice API design patterns. Emphasizes functional-style programming with C# 12+ features.

Analyze code coverage and CRAP (Change Risk Anti-Patterns) scores to identify high-risk code. Use OpenCover format with ReportGenerator for Risk Hotspots showing cyclomatic complexity and untested code paths.

Create implementation tickets with proper format and conventions.

Generate Claude Code native Tasks from an existing spec. Use when user says "create tasks", "generate tasks from spec", "spec to tasks", "task generation", or wants to decompose a spec into implementation tasks.

This skill should be used when the user asks to 'create a task from', 'add issue for', 'track work on', or provides conversational task descriptions like 'I need to fix the blog bug' or 'remind me to update the docs'. Converts natural language task descriptions into structured beads with automatic categorization, priority inference, and optional blocking relationships.

Create hyper-detailed task specifications with embedded context, eliminating implementation lookups. This skill should be used for breaking features into implementable tasks with complete architecture references.

Use this skill when you need to add a new LEAN QCAlgorithm strategy in Python.

Use to decompose user stories into individual development tasks. Creates task documents that can be assigned, estimated, and tracked.

Create comprehensive steering documents for development projects. Generates project-specific standards, git workflows, and technology guidelines in .kiro/steering/ directory.

Guide for creating coding standards via the Packmind CLI. This skill should be used when users want to create a new coding standard (or add rules to an existing standard) that captures team conventions, best practices, or coding guidelines for distribution to AI coding assistants.

Create custom Semgrep rules for vulnerability detection. Use when writing new rules for specific vulnerability patterns, creating org-specific detections, or building rules for novel attack vectors discovered during bug bounty hunting.

Smart code scanner that detects Spring Boot patterns and routes to appropriate skills. Auto-invokes when editing Java or Kotlin files in Spring Boot projects, working with pom.xml/build.gradle containing spring-boot-starter, or when context suggests Spring Boot development. Detects annotations (@RestController, @Entity, @EnableWebSecurity, @SpringBootTest) to determine relevant skills and provides contextual guidance. Uses progressive automation - auto-invokes for low-risk patterns (web-api, ...
